  1. HERWIG validation report ATLAS MC Validation Meeting, 24 May 2011 Responsibles: Jon Butterworth (UCL), Claire Gwenlan (Oxford), Daniela Rebuzzi (Pavia, INFN) Today: validation for MC11 (16.6.5.Y, AUET2-LO** tune, HERWIG 6.520) (SM validation: D. Rebuzzi; SUSY validation: C. Gwenlan)

  2. Fortran HERWIG validation AIM • Validation of athena 16.6.5.Y (including MC10JobOptions to MC11JobOptions migration, change to new evgen transform Generate_trf.py, HERWIG version update and new AUET2-LO** tune) for MC11 production • Check impact of new “AUET2-LO**” tune for Herwig/Jimmy • details documented in ATL-PHYS-PUB-2011-008 NB HERWIG version updated to 6.520 for MC11 [majority of updates in 6.520 already in our patches for 6.510] • validation samples • 15.6.14.7, MC10JobOptions, AUET1 tune (Baseline MC10 sample) • 16.6.5.3, MC11JobOptions, AUET1 tune [checking athena and HW version updates only] • 3. 16.6.5.3, MC11JobOptions, AUET2-LO** tune Conclusion: no problematic issues observed 1

  3. HERWIG SUSY validation • Validation SampleBs (50k events) • mc10_valid.105403.SU3_jimmy_susy.recon.AOD.e787_a124 (MC10JOs, 15.6.14.7, AUET1 tune) • private samples (MC11JOs, 16.6.5.3, HW 6.520, AUET1 tune) • mc11_valid.105403.SU3_jimmy_susy.recon.AOD.e789_a124 (MC11JOs, 16.6.5.3, HW 6.520, AUET2) example: dilepton mass (OSSF) ratio of black/red SUSY validation: all distributions looks sensible and within expectations (one small issue I would like to understand a bit better – see later) 2

  4. HERWIG SUSY validation Some more examples (further plots in extras) – look OK MET number of events number of events Anti-Kt4 truth jets number of events number of events electrons 3

  5. HERWIG SUSY validation Possibly some observable difference in e.g. jet multiplicity • Trend appears more to do with athena/HERWIG update than due to PDF/tune change i.e. green and black, run in same athena version but with different tunes, look similar pT > 20GeV, |eta|<5 number of events Anti-Kt4 4

  6. Summary validation status: • 16.6.5.3 (MC11JobOptions) checked against baseline of 15.6.14.7 (MC10JobOptions) • Log files visually checked to ensure correct parameter settings ✔ • Distributions look sensible given new PDF/tune (and HERWIG version) • AUET2-LO** tune vs AUET1-LO* (using 16.6.5.3; MC11JobOptions) • Some differences observed in e.g. jet multiplicities – appears to be to do with (athena/)HERWIG update rather than tune • (differences are likely understandable; will perform some more checks to pin down in next couple of days) 5
